« Continental unveils AllCharge charging system; using the EV powertrain as a universal charger; up to 800V and 350 kW and all types of stations | Main | NEVS starts city mobility pilot with new 9-3 EV series in Tianjin; launching SUV model » A joint study by Controlled Power Technologies (CPT) and Austria’s Technische Universität Wien (TU Wien) into 48V diesel mild hybrid technology verified a 9% reduction of NO in raw engine-out emissions, while retaining the fuel economy and CO benefits of diesel engine technology. The cost effectiveness of this approach is further underscored by its impact on lean NO trap (LNT) and selective catalytic reduction (SCR) aftertreatment systems, which have less raw NOx emissions to process, potentially allowing for a reduction in exhaust system cost and complexity, and a longer service life. Belt-integrated starter-generator (BISG) systems have already been successfully applied by the industry to reduce CO emissions by the simple expedient of stop-start. In principle, the same low voltage technology can be used to modify the load on the engine and optimize its performance for minimal NO and particulate emissions. The challenge is having a fast-enough response time for real world driving conditions. CPT’s switched reluctance technology is by its very nature fast acting as well as highly controllable, and well-suited to optimizing diesel and gasoline engines for minimal NO and particulate emissions, the company said. Not only does lower raw emissions of NO reduce the load on an SCR system—and hence the continuous consumption of ammonia (AdBlue) used as the reducing agent—but also has the potential to reduce the active catalytic components, which are usually precious metals. A switched reluctance machine might even allow the use of an LNT solution rather than requiring the more expensive SCR system. Diesel exhaust systems can also include a diesel particulate filter (DPF), which may also require less frequent purging. The CPT-TUW study evaluated the switched reluctance technology to the Worldwide Harmonised Light Vehicles Test Procedure (WLTP)—the latest compliance requirement for any new cars launched onto the EU market from September 2017 onwards. WLTP defines a globally harmonised standard for determining the levels of pollutants and CO emissions, as well as fuel or energy consumption. The CPT-TUW study not only considered elements such as the belt ratio, but also the thermal efficiency of the water-cooled BISG, as well as vehicle operational patterns over additional test cycles. The boosting provided by the BISG came only from energy recovered during recuperation events, with a balanced battery state- of-charge and a constant vehicle electrical load applied of 300W. CPT is further validating its technology over the Real Driving Emissions (RDE) test cycle, which being even more robust should demonstrate the potential for further improvements of its SRMs. Like mild hybrid systems generally, CPT’s SpeedStart technology harvests kinetic energy when the vehicle decelerates, which is then reapplied as torque by the switched reluctance machine during accelerations to offset fuel burn in the combustion engine. The advanced electronic control offered by an SRM, however, can further influence the engine operating point by absorbing or supplying electrical energy to move the combustion engine into a more favorable operating region. The benefits are achieved, because an SRM machine can respond swiftly to fast changing and transient road conditions. The control strategies being developed and refined by CPT are based not only on this latest study, but also numerous other R&D programs, as well as extensive real world driving and vehicle systems simulation work. This enables interrelated systems, such as battery management, exhaust aftertreatment and complementary thermal energy recovery, to be operated seamlessly, while also providing a valuable computer-aided engineering capability to explore further potential avenues of development through 48V electrification. Not only applicable as original equipment in cars, CPT’s switched-reluctance technology is also being tested in trucks and buses and off-highway vehicles.

Petty crimes pose a more significant threat to daily life of local communities. Crime increases due to socioeconomic criteria (wealth level of local community, unemployment rate, etc.) and its impact is becoming more critical due to recent economic crisis. This high rate of criminality infects the social and commercial environment which makes citizens and business reluctant to elaboration and welfare. Moreover, it should be kept in mind that reckless confrontation to petty crimes by police or security enterprises can cause unreasonable loss of lives. FP7-SEC-2013 has identified this need and requires low cost technology based solutions that reduce criminal activity and at the same time meet the needs and financial expectations of the communities, citizens and businesses. In response to the above issue P-REACT proposes to research and develop a sensor data (video and motion) capturing and archiving network/platform that allows the protection of small businesses from petty crimes. It is based on low cost components and built in capabilities (sensors and embedded systems) interconnecting using established and emerging technologies, such as Digital Subscriber Lines and Cloud computing. The basic idea is to install low-cost cameras and smart sensors in the small business premises, that are networked directly to, one or more, Cloud-based, Data Centers, where their activity is continuously monitored and recorded. A potential incident detected by sensors installed in a specific store may also trigger neighbour sensors installed in other premises near the incident in order to provide the best coverage possible in terms of data gathering. Moreover, the platform will be able to receive information (images, video) captured by mobile smart devices (phones, tablets etc.) operated by users that were found ad-hoc at a place of an incident.

This project will explore the potential of walking and cycling tracking services to promote walking and cycling mobility. We will focus on established walking and cycling promotion measures and thoroughly assess the potential of ICT based tracking services to overcome barriers to implementation and finding new factors driving the effectiveness of those measures. Through specific research, the related ICT challenges like scheme dynamics, privacy, trust, low-cost, interoperability and flexibility will be tackled for each type of measure. The measures to target will be established measures to promote walking and cycling travel to workplace, shopping, school and leisure promotion measures. We will investigate both the ability that tracking tools may have to address traditional challenges of these measures and their potential to bring new features in the fields of awareness raising, financial/tax incentives, infrastructure planning and service concepts. A common, flexible and open access tool will be developed to provide an ICT input and output platform that addresses the related ICT challenges. Over this platform it will be easy for anyone to build products based on tracking services tailored to the requirements of the specific measures. This project will develop and test a representative set of such products in real measures underway. These test cases will at the same time validate and provide additional inputs for the projects research issues and trigger the widespread of tracking services to support walking and cycling measures in Europe. Users, policy makers and walking and cycling practitioners and final users will be deeply involved in all stages of the project.

We used an aqueous leaf extract of Memecylon edule (Melastomataceae) to synthesize silver and gold nanoparticles. To our knowledge, this is the first report where M. edule leaf broth was found to be a suitable plant source for the green synthesis of silver and gold nanoparticles. On treatment of aqueous solutions of silver nitrate and chloroauric acid with M. edule leaf extract, stable silver and gold nanoparticles were rapidly formed. The gold nanoparticles were characterized by UV-visible spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDAX) and Fourier transform infra-red spectroscopy (FTIR). The kinetics of reduction of aqueous silver and gold ions during reaction with the M. edule leaf broth were easily analyzed by UV-visible spectroscopy. SEM analysis showed that aqueous gold ions, when exposed to M. edule leaf broth, were reduced and resulted in the biosynthesis of gold nanoparticles in the size range 20-50 nm. TEM analysis of gold nanoparticles showed formation of triangular, circular, and hexagonal shapes in the size range 10-45 nm. The resulting silver nanoparticles were predominantly square with uniform size range 50-90 nm. EDAX results confirmed the presence of triangular nanoparticles in the adsorption peak of 2.30 keV. Further FTIR analysis was also done to identify the functional groups in silver and gold nanoparticles. The characterized nanoparticles of M. edule have potential for various medical and industrial applications. Saponin presence in aqueous extract of M. edule is responsible for the mass production of silver and gold nanoparticles.
